I recently copied the set of demo installers present on my old Super Collapse II CD. Some of these games I've never heard of and can't really find online, others are simply aging games from a somewhat-lesser-known company. All of these are limited in terms of how many times they can be run (generally either 10, 15 or 20 runs depending on the game). Included is a Google Drive share of these demo installers exactly as they were on the CD. I have tested them on both Windows 10 and Windows ME and they only generally ran on ME despite installing without error on 10. Still more testing to do since there's a decade-and-a-half gap between those two operating systems, but compatibility is definitely breaking.
